Reboot has been posted to youtube[1] and twitch according to the notes on that YT page.
In a reddit post on the above[2], I came across information that there is an 8-part documentary[3] on Reboot coming out from September 24th, along with a remaster of the series soon.[4]
That documentary sounds great, thanks! I hope they cover the remastering process, as I expect the challenges of using 90s 3D data formats on modern computers are nothing to sneeze at.
